Rotation, and the elevator 150, which was at the lower limit position as the transfer screw 140 rotates, rises upward.

At the same time, ascending with the elevator 150, the card sensor 160 irradiates the light to the stacked cards, receives the light reflected from the stacked cards and outputs a second card number detection signal to the controller.

The control unit receiving the first card number detection signal and the second card number detection signal displays a corresponding card number on the display unit (not shown) when the first card number detection signal and the second card number detection signal coincide with each other. If it does not match, error information is output to the display.

On the other hand, when the elevator 150 is continuously raised to contact the upper limit switch 182, the upper limit switch 182 outputs an upper limit position signal to the control unit, the control unit receiving the upper limit position signal in this way is a motor The driving of the driving motor 120 is turned off by outputting a motor driving off control signal to a driving circuit (not shown).
